OEM 800167077 The XCMG Diamond-Shaped Pin 800167077 is a genuine OEM alignment pin engineered to locate and lock mating structural parts precisely on XCMG hydraulic excavators.
Identified by part number 800167077, this factory-machined pin features a diamond-shaped profile that resists rotation after installation.
It is produced from high-strength steel, ground to an accurate working diameter, and finished with a protective coating for long outdoor service.
Exact OEM profile, length, and chamfer allow direct replacement without filing, reaming, or opening the mounting bore on site.
By fixing part position and preventing rotation, this diamond-shaped pin relieves shear load from bolts and keeps joints stable under vibration.
The 800167077 Diamond-Shaped Pin is machined from high-strength steel that resists shear, bending, and surface wear under heavy machine load.
Its diamond-shaped body bites into the mating bore, so the pin cannot rotate and the joint stays locked in its designed orientation.
A chamfered lead-in guides the pin straight into the hole, which speeds assembly and prevents edge galling on the bore surface.
A zinc or oxide finish protects the steel from moisture, mud, and salt, keeping the pin free of rust during long outdoor service.
Because the pin carries shear load, the surrounding bolts keep their clamp force instead of loosening under constant vibration.
Exact OEM dimensions allow direct replacement, so components line up as designed and no reaming or hole correction is needed.
Production starts with certified steel bar stock checked for chemical composition, hardness, and diameter before machining begins.
CNC turning and milling form the diamond profile, then grinding brings the working diameter into the tolerance band set by the XCMG drawing.
Surface roughness is monitored because a smooth pin seats without scoring the bore, while the diamond flats hold against rotation.
Inspectors measure diameter, profile width, length, and chamfer angle with calibrated gauges throughout the production run.
Traceability records link each 800167077 pin to its steel lot and machining batch, so any deviation can be identified and corrected.
Bolts clamp parts together, but they are not designed to locate them precisely or stop rotation under shear load.
Without an anti-rotation pin, mating parts can creep, which increases bolt stress and leads to fretting, oval holes, and loose joints.
The genuine 800167077 fixes both position and orientation, so bolts only provide clamp force and the joint stays aligned through vibration.
Accurate location also keeps brackets and covers in their designed position, which protects seals, hose routing, and clearances.
Correct alignment reduces wear at mating faces, lowers noise, and makes future disassembly and reassembly faster and more predictable.
The 800167077 Diamond-Shaped Pin installs with standard hand tools, keeping downtime and labour costs low during scheduled service.
Park the excavator on firm level ground, lower the attachment, release hydraulic pressure, and lock out the machine before work.
Clean both bores and remove burrs, rust, or paint so the pin enters smoothly and seats to full depth without binding.
Align the mating holes and the diamond flats, insert the pin by hand or with a soft mallet, and press it home until seated.
Fit the retaining bolts and tighten them to the torque value listed in the workshop manual, then confirm there is no play.
During routine maintenance, check pins for looseness, rust, or wear marks, and replace any pin that no longer holds alignment.
Every 800167077 pin is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel bar to packed product.
Incoming steel is tested for hardness and composition, and finished pins are checked for diameter, profile width, and chamfer geometry.
During production, gauge checks are performed at set intervals so dimensional drift is corrected before the batch is completed.
Post-production checks include visual inspection, coating thickness measurement, and a trial fit in the XCMG alignment fixture.
Sample pins from each batch undergo shear and salt spray testing to confirm strength and corrosion resistance in field conditions.
Generic pins often use softer steel or loose dimensional tolerance, so they wear, shear, or allow the joint to shift and rotate.
A pin without the correct diamond profile cannot stop rotation, which overloads bolts and can enlarge the hole in a soft casting.
The genuine 800167077 is machined to the XCMG drawing, so profile, hardness, and length match the original part exactly.
Using genuine XCMG parts also preserves warranty coverage, protects resale value, and maintains compatibility with other components.
Backed by XCMG quality standards and technical support, this diamond-shaped pin delivers dependable alignment in harsh conditions.
Choosing the genuine 800167077 pin prevents small alignment and rotation problems from turning into expensive structural repairs.
A worn pin lets brackets move and rotate, and moving brackets can chafe hoses, misalign covers, and crack mounting welds.
Durable steel and proper coating keep fit and alignment consistent across a long service life, reducing replacement frequency.
Reliable alignment also extends bolt, bracket, and panel life, lowering the total cost of ownership for fleet operators.
Fleet records show genuine XCMG hardware reduces rework and repeat torque checks after major component repairs.
XCMG applies sustainable manufacturing to the 800167077 pin through recyclable steel content and efficient machining processes.
The long service life of the pin reduces material waste and lowers the environmental footprint of replacement parts over time.
Keeping joints aligned prevents hose and seal damage, which supports cleaner operation on sensitive construction sites.
Steel and coating materials in this component meet RoHS and REACH rules for safe handling and responsible disposal.
The 800167077 Diamond-Shaped Pin is held in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Each pin is bagged and packed in a sturdy carton that protects it from moisture, dust, and impact during transport and storage.
For fleet-wide orders, XCMG provides volume pricing and consolidated freight options that simplify planning and reduce cost.
Real-time stock visibility and dedicated supply chain support help fill urgent requests quickly, shortening downtime on active projects.
Robust packaging preserves factory condition until installation, preventing coating damage and edge burrs common in stored spares.
The XCMG 800167077 Diamond-Shaped Pin is a vital alignment component for XCMG excavators, fixing mating parts precisely in demanding conditions.
Its diamond profile, high-strength steel body, and protective coating deliver dependable anti-rotation performance in hot, wet, and dusty environments.
By keeping joints aligned and relieving shear load from bolts, this pin reduces downtime, lowers maintenance costs, and extends machine life.
